I wonder if anyone could provide any advice.

I want to use the copier in a novel way to help put images on ceramics.
To do this I need to get the image out without the toner being fused to
the paper, I can then transfer the toner to the clay and after firing
the image appears!

I have disconnected the power to the heat roller but then the copier
refuses to work.
The copier is an old AEG Olympia Omega 1210Z.
I'm sure there must be a way of overriding this failsafe device but
have not been able to work it out so far.

I would really appreciate it if anyone had any ideas how i could do
this.
